Manager Rick Renteria told ESPNChicago.com Saturday the team is sending Ramirez down to get some rest. Renteria expects Ramirez to be used sparingly while at Iowa, and should be back in the majors after the minimum of 10 days down is up.
Ramirez has been arguably the Cubs' best reliever this season, posting an 0.96 ERA and 0.93 WHIP in 28 innings of work.

Matsuzaka had an MRI taken on the elbow Friday, which apparently showed enough damage to require a trip to the disabled list. The extent of the injury beyond that is not yet known.
Following Friday's start against the Rays,
"I don't think anything, especially in Boston, can surprise you," Lester said. "We all understand where we’re at, we understand it's a business. And (general manager Ben Cherington) and ownership have to do what's right for this organization and if that means whoever it may be is traded for prospects or other guys or whatever, that's just part of the business. We all understand it."
Lester's deal expires at the end of the season. In 21 starts, the left-hander is 10-7 with a 2.52 ERA and a 1.12 WHIP over 143 innings of work. His next start will come Wednesday at home against Toronto.
